| titleOfInvention | Method for synthesizing benzofuran derivatives from phenol and α-halogenated ketones |
| abstract | The invention provides a method for efficiently preparing benzofuran derivatives by using phenol and α-halogenated ketones as raw materials, and reacting in the next step under the action of titanium tetrachloride, that is, adding phenol and polyfluoroalcohol under the protection of inert gas, Then heating and stirring to reflux, adding titanium tetrachloride, and finally dropping a mixed solution of α-haloketone and polyfluoroalcohol, and separating and purifying to obtain the benzofuran derivative after the reaction. The synthesis method of the invention has the advantages of easily available raw materials, low cost, mild reaction conditions, simple and easy-to-control operation, less side reactions, simple post-processing, high product yield, greatly saving production cost, and having good economical efficiency. Benefit, suitable for large-scale industrial production. |
